+**Goal:** Make production initialization use Alembic as the only schema source and seed exactly one protected administrator account with no preloaded business data.
 
 **Architecture:** A dedicated initialization entrypoint will run migrations and seed the protected administrator. The runtime backend container will stop relying on production startup side effects for database structure, and the user-management API will enforce immutability rules for the protected administrator account.
